Subject: FT: Fix RRB messages to use correct endianness
X-Git-Tag: hostap-1-bp~1264
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e9501a07c629ffb7e3448dae9189793b9031bc50;p=thirdparty%2Fhostap.git

FT: Fix RRB messages to use correct endianness

The pairwise cipher field is supposed to be little endian, but the
message building functions did not swap the bytes on big endian
hosts while the message processing functions did. Fix this by using
little endian byte order in both places.
